FLUSH- TANK.

SPEGIFIGATION forming part of Letters Patent No. 223,826, dated January27, 1880.

Application filed July 24, 1879.

To all whom it may concern:

Be it known that I, GEORGE E. WARING, Jr., of the city of Newport, inthe State of Rhode .Island, have made a new and useful Improvement inFlush-Tanks for the flushing of drains, of which the following is such aclear and exact description as will enable others skilled in the art towhich it most nearly appertains to make and use the same, when taken inconnection with the accompanying drawings.

Figure 1 is a perspective view, and Fig. 2 a plan, ofmy improvedflush'tank. Fig. 3 is a longitudinal sectional view of the same.

Like letters indicate like parts in both.

Flush-tanks have been used for some years for the purpose of retainingthe flow of drainage or sewage until a certain amount is accumulated inthe tank, and then discharging the accumulation suddenly and rapidly bythe ac tion of a siphon, by the-withdrawal of a plug, by the opening ofa valve, or by the tilting of a tumbler-tank, iii such amauner as tocause a cleansing-flow to pass through a drain be yond. v

It is found in practice that grease and other accumulations smear, siltup, and otherwise obstruct the operation of these various devices, andcontribute lumps of undissolved matters to the flow in such a manner asto render the drain liable to become obstructed by their deposit.

Grease-traps or settling-basins have been used for the purpose ofwithholding the grease and other obstructing material, allowing only theliquid portions of the sewage to pass into the drain. These grease-trapsonlypartially accomplish the desired purpose, for the reason that theyhave no provision for accumulating an amount of sewage, and by its rapiddischarge causing a cleansing-flow into the drain beyond. I

My invention does away with the danger of obstructing the flush-tank orthe drain beyond it,

the course of the same drain a flush-tank and a grease-trap, the latterbeing nearest to the source of the sewage, in such a manner that thegood offices of both may be secured.

In the figures, A B represent the combined grease-trap and flush-rank,in which A is the grease trap; B, the flush-tank; O, a partitionwallseparating the two; I), a pipe having its inlet below its outlet; E, theinlet, or drain, or sewer on the side toward the source of the sewage,and F the-siphon by which the flushtank B is emptied of its contents.This siphon is not an essential part of my invention, as the dischargemay be effected by the use of a tumbler-tank or valve or other device.

I do not wish to confine myself to the method of construction indicatedherein. It is not the same structure. They may be separate structures,located at any convenient points in the course of the drain or sewer,the purpose in View being, first, to receive the drainage into some formof grease-trap or settling-basin having a suitable device for deliveringthe liquid portion and retaining the solid portion, and in combinationwith this, and fartherdown the drain, to have some form of flush-tank bywhich the discharge may be accumulated and delivered with rapidity intothe drain. beyond.

What 'I claim as new, and desire to secure by Letters Patent or" theUnited States, is-

The combination ofa grease-trap and a flushtank in the course of a drainor sewer, substantially asand for the purpose specified and set forth.
